I just recently bought 18x8 rimsfor my S90 and i was wondering if anyone could tell me what size tires i might need? i was thinking 225/40-18 but im not sure any help would be great : )

I checked at www.tirerack.com and they call for a 225/40/18 for 18" wheels. When I replaced the 16" with 17" wheels on my S60 I went from a 205/55/16 to a 225/45/17, a full 10mm drop. I'm surprised that they only call for a 5mm drop but I'll defer to their expertise. After all, tires and wheels are their business.

Yea i see what you mean, and tire rack is a very good website 9 or so ive heard) once i get tires ill post some pics foreveryone

Would like to see them. If you want you can check out my upgrades in the Sights & Sounds under wheel upgrade S60 850
